Kubernetes官网

在 Linux 系统中安装并设置 kubectl | Kubernetes准备开始 kubectl 版本和集群版本之间的差异必须在一个小版本号内。 例如：v1.30 版本的客户端能与 v1.29、 v1.30 和 v1.31 版本的控制面通信。 用最新兼容版的 kubectl 有助于避免不可预见的问题。在 Linux 系统中安装 kubectl 在 Linux 系统中安装 kubectl 有如下几种方法：用 curl 在 Linux 系统中安装 kubectl 用原生包管理工具安装 用其他包管理工具安装 用 curl 在 Linux 系统中安装 kubectl 用以下命令下载最新发行版：x86-64 ARM64 curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl" curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/arm64/kubectl" 说明： 如需下载某个指定的版本，请用指定版本号替换该命令的这一部分： $(curl -L -s https://dl.k8s.io/release/stable.txt)。例如，要在 Linux x86-64 中下载 1.30.0 版本，请输入：curl -LO https://dl.k8s.io/release/v1.30.0/bin/linux/amd64/kubectl 对于 Linux ARM64 来说，请输入：https://kubernetes.io/zh-cn/docs/tasks/tools/install-kubectl-linux/使用Isaac Sim进行DNN图像分割教程

一.设置Docker、安装NVIDIA工具包、容器部署

这里我在别的地方写过，在下方链接的第二章内容中

二.跟着官网再走一次

我因为想拿到图像分割的掩码，于是跟着官网走Tutorial for DNN Image Segmentation with Isaac Sim — isaac_ros_docs documentation

提示要先完成isaac_ros_unet — isaac_ros_docs documentation 中1~9的内容，于是我又去这个网站

这里又要我根据 Developer Environment Setup — isaac_ros_docs documentation 说明来设置开发环境，好吧继续

在上文链接中我已经配置好了docker，继续走下一步

接下来是https://nvidia-isaac-ros.github.io/getting_started/dev_env_setup.html中的环境设置部分：

1. On x86_64 platforms:

   1. Install the nvidia-container-toolkit using the instructions.

   2. Configure nvidia-container-toolkit for Docker using the instructions.

   On Jetson platforms: Follow this instruction to first set your Jetson up with SSD, then come back to this document and resume from Step 2.

2. Restart Docker:

   sudo systemctl daemon-reload && sudo systemctl restart docker

3. Install Git LFS to pull down all large files:

   sudo apt-get install git-lfs

   git lfs install --skip-repo

4. Create a ROS 2 workspace for experimenting with Isaac ROS:

   For Jetson setup with SSD as optional storage:

   mkdir -p  /ssd/workspaces/isaac_ros-dev/src
   echo "export ISAAC_ROS_WS=/ssd/workspaces/isaac_ros-dev/" >> ~/.bashrc
   source ~/.bashrc
   

   mkdir -p  ~/workspaces/isaac_ros-dev/src
   echo "export ISAAC_ROS_WS=${HOME}/workspaces/isaac_ros-dev/" >> ~/.bashrc
   source ~/.bashrc
   

   We expect to use the ISAAC_ROS_WS environmental variable to refer to this ROS 2 workspace directory, in the future.

To further customize your development environment, check out this guide.

很好走完了，接下来去做图像分割的前置步骤：

1. Clone isaac_ros_common and this repository under ${ISAAC_ROS_WS}/src.

   cd ${ISAAC_ROS_WS}/src
   

   git clone https://github.com/NVIDIA-ISAAC-ROS/isaac_ros_common.git
   

   git clone https://github.com/NVIDIA-ISAAC-ROS/isaac_ros_image_segmentation.git
   

2. Pull down a ROS Bag of sample data:

   cd ${ISAAC_ROS_WS}/src/isaac_ros_image_segmentation && \git lfs pull -X "" -I "resources/rosbags/"
   

3. Launch the Docker container using the run_dev.sh script:

   cd ${ISAAC_ROS_WS}/src/isaac_ros_common && \./scripts/run_dev.sh
   

4. Install this package’s dependencies.

sudo apt-get install -y ros-humble-isaac-ros-unet ros-humble-isaac-ros-triton ros-humble-isaac-ros-dnn-image-encoder

1. Download the PeopleSemSegNet ShuffleSeg ETLT file and the int8 inference mode cache file:

   mkdir -p /tmp/models/peoplesemsegnet_shuffleseg/1 && \cd /tmp/models/peoplesemsegnet_shuffleseg && \wget https://api.ngc.nvidia.com/v2/models/nvidia/tao/peoplesemsegnet/versions/deployable_shuffleseg_unet_v1.0/files/peoplesemsegnet_shuffleseg_etlt.etlt && \wget https://api.ngc.nvidia.com/v2/models/nvidia/tao/peoplesemsegnet/versions/deployable_shuffleseg_unet_v1.0/files/peoplesemsegnet_shuffleseg_cache.txt
   

2. Convert the ETLT file to a TensorRT plan file:

   /opt/nvidia/tao/tao-converter -k tlt_encode -d 3,544,960 -p input_2:0,1x3x544x960,1x3x544x960,1x3x544x960 -t int8 -c peoplesemsegnet_shuffleseg_cache.txt -e /tmp/models/peoplesemsegnet_shuffleseg/1/model.plan -o argmax_1 peoplesemsegnet_shuffleseg_etlt.etlt
   

3. Create a file called /tmp/models/peoplesemsegnet_shuffleseg/config.pbtxt by copying the sample Triton config file:

   cp /workspaces/isaac_ros-dev/src/isaac_ros_image_segmentation/resources/peoplesemsegnet_shuffleseg_config.pbtxt /tmp/models/peoplesemsegnet_shuffleseg/config.pbtxt
   

4. Run the following launch files to spin up a demo of this package:

   ros2 launch isaac_ros_unet isaac_ros_unet_triton.launch.py model_name:=peoplesemsegnet_shuffleseg model_repository_paths:=['/tmp/models'] input_binding_names:=['input_2:0'] output_binding_names:=['argmax_1'] network_output_type:='argmax' input_image_width:=1200 input_image_height:=632
   

   Then open another terminal, and enter the Docker container again:

   cd ${ISAAC_ROS_WS}/src/isaac_ros_common && \./scripts/run_dev.sh
   

   Then, play the ROS bag:

   ros2 bag play -l src/isaac_ros_image_segmentation/resources/rosbags/unet_sample_data/
   

5. Visualize and validate the output of the package by launching rqt_image_view in another terminal: In a third terminal, enter the Docker container again:

   cd ${ISAAC_ROS_WS}/src/isaac_ros_common && \./scripts/run_dev.sh
   

   Then launch rqt_image_view:

   ros2 run rqt_image_view rqt_image_view
   

   Then inside the rqt_image_view GUI, change the topic to /unet/colored_segmentation_mask to view a colorized segmentation mask.
